Sedge-Moss type of wetland produced where slightly alkaline water emerges at the surface Peat-forming freshwater wetlands are generally non-acidic, receive nutrients mainly from groundwater sources, and are dominated by marsh-like vegetation.

Type of wetland that accumulates peat deposits; they are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium.

Type of wetland that accumulates peat deposits Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium.

Wetlands that receive nutrients via direct contact with mineral enriched groundwater A 'poor' fen has very low concentrations of plant nutrients and floristically resembles a bog A 'rich' fen has relatively high concentrations of nutrients, but is still characterized by the accumulation of peat.

Type of wetland that builds up peat and receives some drainage from surrounding mineral soils and supports marsh like vegetation.

An open or lightly treed wetland habitat, more mineral-rich than a bog due because of available groundwater; typically acidic to alkaline.

Type of wetland that accumulates peat deposits Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium Source: US EPA.

Nutrient rich, organic wetland influenced by mineral-bearing groundwater Forms a moderately decomposed peat near the top The surface is usually level and mostly covered with sedges, brown mosses, grasses and willow and birch trees and shrubs.

Low marshy or flooded area of land.

Wet peatland with water mainly coming from groundwater; without sphagnum moss.

Forsythe-Edwards-Notation.

Low-Lying wet land with grassy vegetation; usually is a transition zone between land and water; 'thousands of acres of marshland'; 'the fens of eastern England'.

Sedge or reed dominated peatland, often with some shrubs or small trees, characterized by mineral-rich, aerated waters at or near the surface Fens with lower calcium content often evolve into Sphagnum lawns and, eventually, acid bogs An Old English word.

Mire that receives water from the surrounding land and hence nutrients from rocks and soils Because of this, a fen supports different communities of plants and animals than a BOG.

Habitat composed of woodland and swamp.

Hyperspace alien species attracted to bright shinny objects and known to mate with space vessels This happened to the Excalibur An alternative definition : A synonym for Babylon 5 fan coined by JMS It is not known if they mate with him.

Wetland fed mainly by groundwater.

Peat accumulating wetland that receives some drainage from surrounding mineral soils and usually supports marsh-like vegetation These areas are richer in nutrients and less acidic than bogs The soils under fens are peat if the fen has been present for a while See also bog, pocosin, swamp, and wetland.

Low marshy land, wetlands, or bog, often partially and/or periodically covered with water Fenland is similar to peat bog but generally has more nutrients in the water supply.

Wetland that is at the watertable and has a direct hydraulic connection to it, fens accumulate peat and the vegetation is dominated by sphagnum moss and small herbs.

Bog with springs as a water source other than precipitation.

Low, marshy or flooded area of land.

Type of wetland having alkaline water and unique plant species.

Plural form of fan, by analogy to man and men Usage: Obsolete.

Type of wetland that accumulates peat deposits, but not as much as a bog Fens are less acidic than bogs, deriving most of their water from groundwater rich in calcium and magnesium.
